Number Of Black Organ Donors Increases In Michigan, Many Blacks Still Reluctant To Donate Organs
Although the number of blacks who are registered as organ donors in Michigan has increased in the last 15 years, many are still reluctant to be organ donors, the Detroit News reports. According to Remonia Chapman, director of Gift of Life Michigan"s minority organ tissue transplant education program, many blacks are hesitant to participate with the organ donor registry because they have inadequate access to health care.Chapman said that increased awareness and education about organ donation and the diseases that lead to the need for donated organs, as well as partnerships with minority donors, black ministers and community groups, have encouraged more blacks to be organ donors. In the last 15 years, the percentage of black Michigan residents who are registered organ donors has increased from 10.8% to 21%, with overall minority registration at 24%. Chapman noted that about 41.3% of people on Michigan"s transplant waiting list and about 46% of people in need of a kidney are minorities.According to the News, minority donors are the best matches for minority organ recipients because the genetic profiles of the donor and recipient will have more similarities. Chapman added that the best matches for kidney recipients are donors from the recipient"s family or from the recipient"s ethnic group if a family donor is not available (Stolarz, Detroit News, 5/19).

New Cognitive Screening Test For Detecting Early Dementia
Researchers at Addenbrook"s Hospital in Cambridge published a study on bmj.com in which they explain their design and evaluation of a new cognitive test for detecting Alzeimer" disease called TYM ("test your memory") which is considered quicker and more precise than many existing tests, and which can also help diagnose early dementia.

What Is Pulmonary Embolism? What Causes Pulmonary Embolism?
An embolism - from the Greek ç©mbolos meaning "stopper" or "plug" - is the term that describes a condition where an object called an embolus is created in one part of the body, circulates throughout the body, and then blocks blood flowing through a vessel in another part of the body. Emboli (plural of embolus) are not to be confused with thrombi (plural of thrombus), which are clots that are formed and remain in one area of the body without being carried throughout the bloodstream.

Expression Of Myoglobin In Human Cancers

A group led by Dr. Alberto Bardelli at The University of Turin Medical School reports that myoglobin may protect against the stresses of tumor growth. This study can be found in the July 2009 issue of the American Journal of Pathology. Myoglobin plays an important role in muscle cells by both transporting oxygen and preventing cell damage by scavenging free radicals. Tumor cells often survive in hypoxic (low oxygen), high free radical environments, despite these stresses on tumor growth. Flonta et al hypothesized that certain cancers may express myoglobin to survive the conditions associated with tumor growth. Indeed, human epithelial tumors, including breast, lung, ovary, and colon carcinomas, expressed high levels of myoglobin at early stages of development. In addition, myoglobin was induced in cell lines subjected to hypoxia, oxidative stress, and mitogenic stimulation. Myoglobin expression in carcinomas may therefore protect against the stresses of tumor growth. Dr. Bardelli and colleagues postulate that "should myoglobin prove to play a causative role in tumor progression, ò€¦ it is tempting to speculate that targeting one or more of its multiple functions by pharmacological agents or more advanced molecular tools could represent a novel therapeutic strategy in oncology."
